Dear All,
What is the meaning of the help of Factor:
Factor[poly,Extension->Automatic] will extend the domain of
coefficients to include any algebraic numbers that appear in poly. =BB
if
Factor[x^2 - 2, Extension -> Automatic]
does not seem to work in the same way as
Factor[x^2 - 2, Extension -> Sqrt[2]]
Thanks,
J=E1nos
